I received full instructions from the host and co-hosts, and they were helpful. The room was clean and tidy, and bed was very comfortable to sleep (neither too hard nor too soft), I slept well for every night despite the bit noisy from outside street. They even offered the kitchenware for you if you would like to cook. There was a little bit strange smell from the kitchen sink drain, but it was not a big deal for me, I put a deodorant in it and hoped they can improve it. The roof top gym and swimming pool opened from 7:00 to 21:30, however, you could access into it all the day (wonderful).
The location is great, just 5-6 mins walk to BTS Phloenchit, and the next station Chit Lom is the center of Bangkok. There are several groups of cheap and delicious street food next to the apartment, they cook alternately day and night, so that you can order 24/7 if you like street food.
Overall, I think they offer a better quality than the price.
